Located off the west coast of Italy and offering sandy beaches, sea and sunshine, Sardinia has long been a popular holiday location for the rich and famous. And, so it seems, with royalty. Last week, Denmark's Crown Prince Frederik and Crown Princess Mary joined holiday makers on the Mediterranean island for a summer break in the seaside resort of Porto Cervo.

But lounging around soaking up the rays was not on the agenda for the pair - arguably Europe's most active royal couple - who were seen zipping around on a jet ski in the Sardinian waters.

Their love of sporting activities seems to have already been inherited by their son. Despite being just three-years-old, Prince Christian – Frederik and Mary's elder child – was not going to miss out out the adreneline-pumping ride, nestling in between his parents on the watercraft.

For two-year-old Isabella - who sat out the water sport on this occasion - the chance to join her big brother and mum and dad will have to wait just a little longer.

While the Copenhagen-based royals were enjoying aquatic activities, footballer Jamie Redknapp and his wife Louise opted for on-shore beach relaxation. On Sunday - two days after Frederik and Mary were seen riding the waves – the loved-up couple joined fellow beach-goers on the sandy coastline of the marine resort.

A favourite destination for the attractive couple, Sardinia was their choice holiday spot back in July last year when Louise was pregnant with their second child. And appropriately, the former Eternal singer, 34, and her football pundit love, 35, chose to head back there seven months after welcoming son Beau Henry.
